THERMOMETER MOUNTING.

Application led September 18, 1922. Serial No. 588,824.

To (LU 'whom t 712,03/ concern.'

Be it known that I, HENRY B. BnowN, Va citizen of the United States, residing at Rochester, in the county of Monroe and State ofl New' York, have invented certain new this specification, and to the reference numerals marked thereon.

This invention relates to measuring` instruments such, for example, as thermometers, and more particularly to the combination of such instruments with suitable means for mounting and supporting the same, one object of the invention being to provide a practical device of this character having the advantages also of economy in manufacture and convenience in use. From f a more particular aspect, 1t is a further object of the invention to provide such an instrument having a mounting `or support comprising an enameled scale plate ad? vantageously combined with the associated parts so as to facilitate the manufacture of the instrument in improved quality and at a relativelyT low cost. To these and other ends the invention consists in certain improvements and combinations of parts, all as will 'be hereinafter more fully described, v the novel features being pointed out in the claims at the end of the specification.

In the drawings; Figure 1 is a front elevation of an instrument embodying the present invention; Figure` 2 is a rear elevation of the same with parts removed;`

Figure 3 is an enlarged sectional kview on i the line 3-3 of Figure 1, and

Figure 4 is an enlarged sectional view on the line 4**-4a of Figure 1.

Similar reference numerals throughout ythe several views indicate the same parts.

The embodiment of the invention at `present preferred and' herein disclosed byl Way of illustration of the principles involved v comprises a combined thermometer and mounting, although 1t 1s to be understood thaty the inventionmay be applied to va- `"rions other types Yof instruments.

*holding the same on the main plate.

with rounded ends and rolled and rearwardly turned margins as shown in the drawings to afford a rigid construction and at the same time present an ornamental and pleasing appearance. The thermometer is shown as comprising a bulb Vportion G and a light pervious stem or tube T, the plate 5 projecting on all sides well beyond the thermometer to protect the same.

It is desirable in a construction of this nature to finish and color the forward side or face ofthe metal plate by a suitable :Iilm or coating such as the vitreous enamel shown at 8, Figure 4, beneath or in which is indelibly marked the usual scale Y8 adjacent and cooperating with the thermometer tube. Means are required for securing the tube on plate 5 and also for the attachment of bracket or other supporting` means to plate 5 preferably at its rear side, but it has been found that if the material of the plate is materially thickened at any point as, for example, by the integral formation therewith of clips or bracket means or the welding of the saine thereto for the purposes indicated, the unequal heating and cooling of the plate caused by such variations in its thickness of material interferes with the uniform application of the enamel or glazing. so that the latter becomes streaked or craked, thereby marring the appearance of the instrument and causing a large waste of material.

It has been found that the above difficulty may be overcomev in a practical and advantageous manner by completing plate 5 separately and subsequently combining therewith a back or supporting plate 10 and securing the thermometer and the back plate to the main plate 5 by devices passed through openings formed in the main plate. To this end a plurality of clips or straps 11 are provided and formed to embrace the thermometerftube as shown in Figure 4 for Two such straps are preferably employed, one located'adjacent each end of the tube Vto clear the scale and the ends of these straps are turned outwardly parallel with the face of the main plate as at 12, Figure 4. The main plate has openings formed therein at these portions and the straps are perforated at their ends and located with the perforations in registry with the openings in the plate to receive suitable means such as small bolts 13 fer securing the parts together and holding the tube immovable on the face of the plate. rlhe latter may be provided with an opening 14, Figure 3, to receive a rearuf'ardly projecting' linger 15 formed at the upper end ot the tube for initially locating the same on the plate, as well understood in the art. The main plate is also preterably formed with an aperture 13 opposite the thermometer bulb tor receiving the latter and altording access ot the atmosphere to all sides thereof.

The back or supporting plate 10 is also preferably secured to the main plate ,by means ot securing devices passed through registering openings in the two plates, and for this purpose use is advantageously made ot the same bolts 13 holding the tube clips. The black plate is therefore provided with openings registering with `bolts 13 which are of suiiicient length to extend beyond the back plate and receive securing nuts 17 which eflectively bind all of the parts together. The construction thus provides tor the stamping out and enameling of the main plate independently of the other parts tor the reasons described above, and the subsequent assembling of the other parts therewith in a convenient and economical manner.

As indicated above the back plate 5 is yprovided with bracket means for supportingthe instrument on a wall or other suitable object preferably having for this purpose a pair ofspaced ears 18, Figures 2 and 3, struck up perpendicularly therefrom and formed with pertorations through which are passed one end of a bracket 19. The present embodiment being particularly .adapted for use as a window thermometer, bracket 19 is turned Lhorizontally as at 2O toispace the instrument from a wall or other surface 21 to which .the other angularly disposed end of the :bracket isattached as .by means Vof screws-22'. The portionQ/O of the bracket sustains the lower supporting ear 18 oit the `back plate and the bracket is extended at its end beyond the other ear andthreaded for the reception of a nut- 23 holding the instrument on the bracket. A. .further .advantage of the provision of a separately formed back plate resides in the fact that the parts, such as ears 18, for connecting the instrument with the bracket supporting means are not subjected to the application of the enamel which would otherwisel tendto partially till and reduce the size of vthe openings in ears 18v for reception of the bracket 19. Such enamel is too hard to permit ot removal without considerable diticulty and it the openings be made larger than required to compensate for such iilling up with enamel a poor and uncertain tit on the bracket results. The

presentliorm of construction. overcomes this diiiculty in a satisfactory manner, and atfords a readily detachable, pivotal form of support for the instrument so that it may be adjusted to the particular angle at which it can be viewed to best advantage.

It is apparent from the above "description and the drawings that the parts are all simple in form and capable of being manu- Jiactured at a relatively low cost. The main or scale plate 5 is separately made with a uniform thickness adapting it to receivethe enamel finish with a high degree of perfection and the various parts may then kbe economically and effectively .assembled .and combined in the manner described. bracketmeans is also simpleand practical in form, and the various parts nof the nstrumentare readily detachable forrepair or lother purposes. The instrument is conveniently adjustable to the angle at which it may be most clearly viewed andits generally simple and harmonious features af- Jford a pleasing appearance.

I claim as my invention:
